Evolution of Earth's Atmosphere

Complete No-Prep lesson with exam questions, tasks and answers on the Composition and Evolution of Earth’s Atmosphere for AQA GCSE (9-1) Science / Chemistry. This lesson covers all of GCSE Chemistry exam spec 4.9.1 and Combined Science to 5.9.1.

As a Secondary Science teacher and Deputy Headteacher for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.

What’s Included:
• Starter / Do Now Activity
• Explanation slides in “chunked” sections.
• Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers.
• Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards.
• Answers for all questions
• All easily editable to adapt to your teaching or to use in existing lessons.
• Slightly humorous, at points, if you like that sort of thing.

Learning objectives:

• Describe the current composition of our atmosphere.
• Describe how the Earth’s early atmosphere formed, and its composition for the first billion years.
• Describe how oceans were formed.
• Explain how photosynthetic life caused Earth’s atmosphere to change over the last 2.7 billion years.
• Explain why the amount of carbon dioxide has changed since the Earth’s early atmosphere.

The lesson was written for AQA GCSE Science / Chemistry but is very likely to be applicable to other exam specifications.
